Hey Ive actually ridden most of the bikes mentioned. I am personally a fan of the DMR drone, its a simple set up with ok components! singlespeed, rigid forks, so would probably do the job for you! Identiti 666s are again ok but as far as im aware quiet abit more money? Kona dirt jump series are all good bikes come set with gear and an entry level marzocchi suspension fork so not bad if youve got abit more money to add for possibly a more comfortable ride. You may want to also look at specialized, ive got a 05 p2 and is really nice bike to ride... i have ridden the new ones which are also nice bikes. The 08s may be abit out of your price range? But if you have a specialized dealer by you then maybe go and have a word see if they can get there hands on an 07 for you which normally come with about £100 off as they are older models. Cheers
